Move logo into partial for easier overriding

[boileaum]

I checked that...

• ... the documentation does not mention anything about my idea
• ... to my best knowledge, my idea wouldn't break something for other users
• ... there are no open or closed issues that are related to my idea

Description

The block

          {% if config.theme.logo.icon %}
            <i class="md-icon">{{ config.theme.logo.icon }}</i>
          {% else %}
            <img alt="logo" src="{{ config.theme.logo | url }}" width="24" height="24">
          {% endif %}

is repeated in material/partial/header.html and material/partial/nav.html and could be factorized into a material/partial/logo.html file using an include statement.

Use Cases

It would make easier to customize the logo area (actually, I spent some time before realizing it was double located...).

This is a great idea but only became possible because of the refactoring we're currently undertaking. If you look closely, you'll see that the width and height values are different, but those shouldn't be necessary anymore for the refactoring branch. For this reason, I just moved the logo into partials/logo.html as you suggested in c9b2c1e

Thanks for the quick correction.
And thanks also for this nice project!

The fix was just released as part of RC 4. See #1498 for details.
